摘要

将相变纳米胶囊与传统建筑围护结构材料进行结合,通过非机械化储能方式提高传统被动式太阳能建筑的集热和控温性能,从而实现室内节能。通过微乳液聚合法制备分别含有3种成核剂（纳米Al₂O₃/C₂₈/C₁₄H₃₀O）改性的C₁₈/SiO₂相变纳米胶囊,并采用浇铸法制备含有最佳相变纳米胶囊的石膏板。通过傅里叶变换红外光谱、X射线衍射和扫描电子显微镜测定相变纳米胶囊的化学结构和外貌,差示扫描量热法、热量分析及激光导热仪探究其储热性能,并对相变纳米胶囊石膏板进行一系列综合热性能测试。结果表明：相变纳米胶囊呈球状,粒径范围为100~300 nm。与不含成核剂的相变纳米胶囊相比,含15% C₁₄H₃₀O成核剂的过冷度降低49.00%,导热系数提高13.76%,并具有优异的热耐久性和可靠性。因此,将15% C₁₄H₃₀O改性的相变纳米胶囊应用于石膏板,通过引入温差评价发现,添加10%相变纳米胶囊的石膏板更有利于充分吸收外界热量,减小温度波动,从而实现被动式太阳能建筑室内节能。

Abstract

Phase change nanocapusules are combine with traditional building envelope materials, which can improve the heat collection and temperature control performance of traditional passive solar buildings through non-mechanized energy storage, thereby realizing indoor energy conservation. Organic modified SiO₂@C₁₈ nanocapusules with different nucleators （Nano-Al₂O₃/C₂₈/C₁₄H₃₀O） were synthesized effectively via the microemulsion polymerization method and the gypsum boards containing phase change nanocapusules were prepared by casting method. The chemical structure and appearance of nanocapusules were determined by FT-IR, XRD, and SEM. The thermal properties were investigated by DSC, TGA and LFA. Principal thermal performances of gypsum boards containing the optimal NEPCMs were measured systematically. The results demonstrates that the phase change nanocapusules are spherical in size range of 100~300 nm. Compared with the NEPCMs without nucleating agents, the NEPCMs containing 15% C₁₄H₃₀O has a superior performance with the supercooling degree reduced by 49.00% and thermal conductivity increases by 13.76%. Meanwhile, its exhibites outstanding thermal durability and reliability. Therefore, contents of 15%C₁₄H₃₀O NEPCMs is added to the gypsum board. Through the temperature difference evaluation, it is founded that gypsum board with 10% NEPCMs is more conducive to absorbing external heat fully, reducing indoor temperature fluctuation and achieving a superb energy-saving effect in passive solar building.
